Cash Flow Calculations
j = the group number of the cash flow.
CF
j
= amount of the cash flow for group j.
nj = #TIMES the cash flow occurs for group j.
k = the group number of the last group of cash flows.
N =
J
L n[ = total number of cash flows prior to group j

k
NPV = CFo + L (CFj x USPV (i%:n

)
x SPPV (i%:N
j
))
j ~ 1
When NPV = 0, the solution for i% is IRR%.
NFV = NPV x SPFV (i%:N) where N
